Quick Perspective

Specify View
  1. To produce a perspective view rather than the command dview it is possible to use the rapid command for the perspective in the Express menu. The perspective gives a realistic representation of the observer's eye vision. The lines that compose the 3D views of objects aren't parallel but convergent or divergent.
To obtain a rapid perspective view
  1. Do one of the following:
  2. Select Express > Tools > Perspective > Specify View.
  3. Type p_perspective and then press Enter.
  4. Specify drawing units.
    If the current visualization isn't plan view, it's automatically set plan view to position the camera and target points.
  5. Specify a camera position. While using the mouse to point out the position of the camera it is possible to perform zoom to magnify or reduce the visualization. The camera is automatically positioned to 160 cms (or 1,6 mt or 1600 mm) elevation.
  6. Specify a target position
Create Auto Perspective
  1. The command automatically calculates the target point, camera position and focal length. The objects nearer to the camera position appear greater and some parts, further from the camera, appear smaller. If the command is repeated and the object is very close, it becomes rather deformed and it could disappear from the screen.
To obtain a rapid perspective view
  1. Do one of the following:
